The ueventd.rc sets permissions to 0664 but init.rc sets cpu0 to
0660. Since lots of processes already had read access for cpufreq nodes
(refer to system/sepolicy/public/domain.te), align all cpus to 0644
permissions.

Delete all files and directories under
/data/misc/virtualizationservice at boot. Originally they were owned
by the virtualizationservice user; we now run as system, and don't
have permission to remove them after boot.

Test: Create fake stale dir+file, see them deleted
Change-Id: I5ff7d055aeeb25ba7693e50876d6b8a830c4bf51
(cherry picked from commit 34ee0c931c)
[1] changed the UID of the virtualizationservice daemon and
/data/misc/virtualizationservice directory to `system`. However, this
can cause a permission denial issue when the directory has stale files
when the device was running a build before [1] and an OTA to [1] (or
above) is attempted. The daemon tries to delete the stale files - which
must have been still labeled as old UID and thus the daemon has no
privileged to delete them.
Fixing this issue by ensuring that the directory is always empty by
init.

Previously, virtualizationservice had its own UID
`virtualizationservice`. As a result, crosvm, which is spawed by
virtualizationservice`, also run as the UID. However, that prevented us
from applying task profiles to the crosvm process because joining a
process to a cgroup requires system UID.
To fix that, virtualizationservice now runs as system UID. As a result,
this directory that virtualizationservice accesses has to change its
owner and group to system.

/dev/kvm and /dev/vhost-vsock are used by crosvm. Previously, it ran as
a custom UID `virtualizationservice`. However, this prevented us from
applying task profiles to the crosvm process because joining a process
to a cgroup requires system UID.
Now, crosvm (and its parent virtualizationservice as well) runs in
system UID. Therefore, the ownership of two device files are also
updated accorgly.

This patch preserves the following parameter values:
* Foreground BFQ weight: 100
* Foreground CFQ group_idle: 0
* Foreground CFQ weight: 1000
* Background BFQ weight: 10
* Background CFQ group_idle: 0
* Background CFQ weight: 200
The foreground BFQ weight in task_profiles.json is the default BFQ
weight. From
https://www.kernel.org/doc/Documentation/block/bfq-iosched.txt:
"weight (namely blkio.bfq.weight or io.bfq-weight): the weight of the
group inside its parent. Available values: 1..10000 (default 100). The
linear mapping between ioprio and weights, described at the beginning
of the tunable section, is still valid, but all weights higher than
IOPRIO_BE_NR*10 are mapped to ioprio 0."

/sys/class/block covers all of dm-[0-9], sd[a-z], mmcblk[0-9].
Use it instead of /sys/devices/virtual/block, which only covers dm
devices.
This allows f2fs tunings to be applied more reliably regardless of
how the userdata partition is set up.
Do note that while everything under /sys/devices/virtual/block are
expected to have correct SELinux labels by AOSP, some under
/sys/class/block are not as it's symlinked to platform-specific paths,
and it is up to the vendors to label them correctly.
Test: Confirm entries under /dev/sys aren't dangling and cp_interval,
gc_urgent_sleep_time, iostat_enable and discard_max_bytes are
all set up properly under FBE, FDE and unencrypted.
